2 Which sequence of rigid motions will definitely work to take triangle GHJ onto triangle STU 7 A Rotate GHJ using center G until GH is lined up with ST and then reflect over aline halfway between GHJ and STU B Translate GHJ by the directed line segment GS Rotate GHJ using S as the center by angle H ST Reflect G HJ over ST NAME C Translate GHJ by the directed line segment GT Rotate GHJ using Tas the center by angle HTS Reflect G HJ over ST D Translate GHJ by the directed line segment GS Translate G H J by the directed line segment HT Translate G HJ by the directed line segment T 3 Reflect triangle STU across line ST Which of these is a valid reason why the image of U will coincide with J A The image of U and J are on the same side of ST and make the same angle with it at T B The image of U and Jare the same distance along the same ray from T C The image of U and I will not coincide after reflection over ST 2019 by Illustrative Mathematics D Line ST is the perpendicular bisector of the segment connecting U and J because the perpendicular bisector is determined by 2 points that are both equidistant from the endpoints of a segment 4 Here is parallelogram ABCD U DATE M B illustrative Mathematics PERIOD 2
